All upstairs and in the garden. And kinda in the living room too. Ah, yes, not forgetting the garage, shed and utility room! :-[
Upstairs - the pigs are in my room. Actually, correction...it is their room and I merely rent it out overnight, so I have somewhere to sleep. The cage takes up half the room (seriously!) but it is quite a small room. The poops under the bed overnight, the toys spread out in my whole room on the floor, in cupboards, behind doors...
Garden - piggy poops and hay where I shake out the fleece and VB!
Living room - Piggy scrapbooks full of pigtures, a few toys waiting to be taken up to them.
Garage - pet store cages (used as travel cages), toys, extras. Salad stuff.
Shed - their run.
Utility room - their spare towels and fleeces. And a few dishes and their salad spinner.
